Each sliding plate section is bordered by a sheet metal rim, which is configured as a tightening band or is a component of sheet metal material with a bottom surface, in order to hold the plates together when cracks form in the refractory material. There is a need to.

ある。PRIOR ART A known slide unit of the above type (see German Patent Application No. 2146677)
In this case, the sheet metal rims of the two sliding plate parts abut against each other, and the edges of these two sheet metal rims are free to move upwards. During operation, this results in the sealing surface not coming into close contact with the stationary lock plate due to the different coefficients of thermal expansion of the refractory material and the sheet metal rim. When the plate is slid, the edge of the metal sheet slides under the through-hole of the stationary locking plate, and the steel hot water in the through-hole comes into contact with the metal sheet. As a result, if the plate slides further, the sealing surfaces are damaged by the solidified adhering steel parts, or replacement of the sliding plate parts is difficult because the sheet metal edges are "welded".

ができる。 According to another embodiment of the invention, the sealing surface of the sliding plate part is provided with a fire-resistant extension projecting beyond the sheet metal rim along a linearly extending peripheral section of the sliding plate part. Expanded. This extension advantageously extends along the narrow side of the rectangle, insofar as the sliding plate part has an approximately rectangular shape. The width of the sheet metal rim can be reduced along the appendage, but if the thickness of the appendage is at most half the thickness of the slide plate, there is a sufficient mounting surface (abutment surface) of the appendage and the existing rim. A favorable relationship between thickness and thickness is obtained. It can also be provided that the sheet metal rim extends along the outer circumferential section of the slide plate part into a circumferential groove on both sides by means of an extension in each case. In this way, the sheet metal rim can be constructed to have a uniform width over its entire length.

The slide unit is movable back and forth in the direction of the arrow in a known manner via a power-transmitting connecting rod 22 which is hinged to the frame 20, and which includes a cast-in plate 10a and a closing plate arranged side by side in a frame opening 21. 10b are slide-guided together against fixed lock plates 2, 3. Casting plate 10a and closing plate 10
b is configured as a flat sealing surface 14 directed towards the upper stationary locking plate 2 . The same applies to the lower side of the two sliding plate parts in connection with the lower fixed locking plate 3 in the three-plate sliding nozzle. The casting plate 10a has a flow opening 11 which coincides with the fixed flow openings 5, 6 in one end position (open position) of the slider shown. The closing plate 10b, on the other hand, is provided with a preferably porous insert 12 at the other end position of the slide between the fixed flow openings 5 and 6. The presence of this porous insert 12 allows gas to be blown into the casting channel when it is closed.
Depending on the position of the slider, the closing device is fully opened, partially opened (throttled) or completely closed in a known manner.

A thin metal plate rim 15 is fitted over the outer periphery of each frame in the form of a frame. This thin metal rim 15
are used to hold the plates in place when cracks form in the refractory material due to the very large heating effects that vary during operation. Since the slide plate portions (casting plate 10a and closing plate 10b) are divided, they can be replaced separately. In particular, the cast-in plate 10a, which is exposed to high wear during drawing, is replaced when the closing plate 10b is in the closed position between the stationary locking plates 2 and 3.

ない。 When operating a sliding nozzle, it is generally necessary to cycle through an open or constricted position and a closed position many times in both directions. In this case, the contact points 13 between the respective slide plate sections must be slid under the molten metal present in the through-hole 5 of the upper fixed lock plate. In order to be able to repeat this without difficulty, the end of the joining element or of each sliding plate part adjacent to the contact point must be specially constructed.

is extended to the contact point 13. The two slide plate parts 10a, 10b are preferably designed identically. That is, they each have a similar additional portion 16 that exceeds the rim thickness. For this purpose, the width of the sheet metal rim 15 is reduced in each case by a linear extension 16 . In order, on the one hand, to maintain sufficient stiffness of the sheet metal rim with reduced width and, on the other hand, to obtain a sufficient contact surface of the extension 16 at the contact sleeve 13, the thickness of the extension 16 is adjusted to the plate thickness. must be less than approximately half the size.
